A collection of mods I've ran across that expand the lore-friendly universe of Skyrim. Adding new story lines or plots or what ever else there may be. Some of these mods will not work with other mods.
Continuation:
I've been using all these mods in-gam

A Collection of 50 mods or less

Collection by Skyrimnut

This is a group of mods that have been tested to work together quite well. I purposefully wanted to keep the collection below 50, so unfortunately, many amazing mods didn't make this group. Some fix minor issues I had with the game. Some droppable quest
